Description

The Nortech NGA-504 is an intelligent, loop-powered addressable sounder and beacon that provides simultaneous audible and visual notification for the NGA series fire alarm systems. Designed to alert occupants in high-noise environments or those with hearing impairments, this dual-action device features adjustable sound outputs up to 100dB(A) and high-efficiency LEDs with low current consumption

Features

  • Individually Addressable: Each sounder/beacon can be assigned a unique address, allowing for complex cause-and-effect programming and localized “Alert” or “Evacuate” signaling.
  • Integrated Short-Circuit Isolator: Automatically detects and isolates a wiring fault on the loop, preventing a single short circuit from disabling other devices.
  • Selectable Tones and Volume: Offers a variety of industry-standard tones and adjustable volume levels, configured either via the control panel or internal switches.
  • Loop Powered: Operates directly from the addressable communication loop, eliminating the need for separate 24V power cables and reducing installation costs.
  • High-Intensity LED Beacon: Provides clear visual warning for noisy environments or to assist the hearing impaired, meeting modern accessibility requirements.
  • Digital Communication Stability: Utilizes a robust protocol that ensures reliable operation even on long cable runs with high electromagnetic interference.
  • Synchronized Operation: The control panel ensures that all NGA-504 units on the loop pulse and sound in perfect synchronization for clear notification.
  • Durable Construction: Housed in flame-retardant red ABS plastic, designed for easy mounting on standard BESA boxes or surface-mounted backboxes.
